That comes at something of a price though, and the chunky bezels mean it’s not the most stylish phone — though we do like the bronze edges. Still, it’s powerful, outstripping most other phones under $300, which makes it the perfect companion for a gaming-happy generation. The camera suffers from poor performance in low light, but is otherwise good. It’s also running on Google’s Android One operating system, which means the phone will be updated with the latest security patches and new features quickly and often, helping to keep your kid’s phone secure. It’s a great choice if solid performance and durability are preferred to flashy looks.
This study investigated the effect of 2.45 GHz microwave radiation (2 h/day for 45 days) on biomarkers within Wistar rats. A significant decrease (P

TRPV1 cation channels are the possible molecular pathways responsible for changes in the hormone, oxidative stress, and body temperature levels in the uterus of maternal rats following a year-long exposure to electromagnetic radiation exposure from mobile phones and Wi-Fi devices. It is likely that TRPV1-mediated Ca2+ entry in the uterus of pregnant rats involves accumulation of oxidative stress and opening of mitochondrial membrane pores that consequently leads to mitochondrial dysfunction, substantial swelling of the mitochondria with rupture of the outer membrane and release of oxidants such as superoxide (O2 −) and hydrogen peroxide (H2O2). The superoxide radical is converted to H2O2 by superoxide dismutase (SOD) enzyme. Glutathione peroxidase (GSH-Px) is an important antioxidant enzyme for removing lipid hydroperoxides and hydrogen peroxide and it catalyzes the reduction of H2O2 to water.

In 2011, the International Agency for Research on Cancer (IARC), a component of the World Health Organization, appointed an expert Working Group to review all available evidence on the use of cell phones. The Working Group classified cell phone use as “possibly carcinogenic to humans,” based on limited evidence from human studies, limited evidence from studies of radiofrequency radiation and cancer in rodents, and inconsistent evidence from mechanistic studies (4).
45. Keep it organized. “Always keep your child’s cell phone charger in the same place. It’s best to find a central location — like maybe the kitchen counter, or a table by the door. Mark the end of the monthly billing cycle on a calendar to remind her how long those dwindling minutes have to last.” – Fayette Woman, 10 Cell Phone Safety Tips for Parents, Fayette Woman; Twitter: @faywoman
A phone's specific absorption rate (SAR) reveals the maximum amount of radiation the human body absorbs from the phone while it's transmitting. SAR testing ensures that the devices sold in the U.S. comply with the Federal Communications Commission (FCC) SAR exposure limit, but the single, worst-case value obtained from this SAR testing is not necessarily representative of the absorption during actual use, and therefore it is not recommended for comparisons among phones. In short, selecting a lower SAR phone will not reliably ensure lower radiation absorption during use. The FCC has more information at Specific Absorption Rate (SAR) For Cell Phones: What It Means For You.
But researchers can make some judgments about the potential for harm based on how WiFi and similar technologies work, as well as on how people tend to use their devices. Those factors do provide some reasons to think that WiFi and Bluetooth devices may be less of a concern, says Leeka Kheifets, Ph.D., a professor of epidemiology at the UCLA School of Public Health who has studied the potential health effects of low-level radiation.
Studies conducted by numerous scientific teams in several nations have raised troubling questions about possible associations between heavy cell phone use and serious health dangers. The World Health Organization has declared that cell phone radiation may be linked to brain cancer. Ten studies connect cell phone radiation to diminished sperm count and sperm damage. Others raise health concerns such as altered brain metabolism, sleep disturbance and behavioral changes in children.
Ok, update: Crownstarqi very kindly sent me 2 cell phone shield stickers, but I originally ordered the 6 pack of much thinner rectangular stickers that I could stick more places. I'm too electromagnetically intolerant to even own a cell phone, so I don't know what to do with these! I don't dare bother them about this, b/c they sent me the shield things all the way from China, but I was really hoping to just put more of the rectangular 6-pack stickers on my laptop, to see if more made a difference. It was a very nice gesture on their part, but I'm now concerned that they thought my initial review was of the shield-shaped stickers, when it was a review for these rectangular ones. I noticed that someone else thought they were ordering the 6-pack, and ended up getting a single shield-shaped sticker, instead. This is very confusing & I'm going to just...count my blessings & get on w/ my life. I don't trust any stickers that make the "negative ion" claim, b/c they're often radioactive. I don't realy know what to say, or what review to give, at this point, but I think Cronstarqi are very kind to have sent me something for the trouble w/ my original order, even though what they sent as a replacement was NOT what I had originally ordered. Maybe this was deliberate? I don't know. The package on the shield-shaped stickers says, "The product can only be used as health care instead of replacing the professional medical treatment." I'm so confused, but thanks anyway, to the seller, and the shield-shaped stickers are very pretty. I'd review them, but I have no cell phone & no verified purchase to back up my review. -Account holder's progeny.

39. Beware of cyberbullying. Cyberbullying is yet another reason to monitor your child’s smartphone usage including call and text message records. While your child may not always tell you when they’re being mistreated by a friend or acquaintance, seeing threatening or bullying messages on your child’s phone will allow you to address issues before they escalate to dangerous levels. “Cyber bullies, adults and children alike, harass others by sending threatening or rude texts to cell phones.” – What Are Some Cell Phone Safety Tips For Kids?, How Stuff Works; Twitter: @HowStuffWorks

We actually debated including some links to some of the worst offenders just to show you how outlandish (and unscientific) the claims they make are, but we couldn’t stomach giving them even a penny of ad revenue. If you want to see how bad things are you can search for “Wi-Fi dangers” on Google where, it becomes clear, the page rank algorithm doesn’t always reward pages with the most scientific merit.
They're ok, though there's a nasty chemical processing smell to the stickers. I'm still not sure they're worth what they're made of. No instructions, testimonials, or even a product insert label, when you get them in a pretty, smelly gold sleeve, though you don't really need instructions for stickers, lol. They're very durable and don't wear easily, despite pressure and contact w/ many surfaces & objects. The price increased $4 since I ordered them. That said, the designs on them are beautiful. I just don't understand what I paid for, & it would be nice if there were tests on devices like this, proving that they actually absorb or render harmless, various wireless frequencies, and at what range. If they were cheaper, I might order 2 more packs just to see if they made a difference if placed closer together in larger quantity. I have 3 on my laptop & have noticed a very slight reduction in sensitivity to EMF. I didn't notice this slight difference until I put 1 sticker where my right hand rests on the keyboard. I had originally placed 2 on the base of the laptop, 1 over the wifi card, & 1 over the processor, and it made zero difference. I left things like that for 2 weeks, before I decided to try putting one of the stickers on the keyboard area. I'm still not clear on whether or not I'd buy this product again, but like the seller, Crownstarqi, b/c they are sending me a few more stickers so that I can see if multiple stickers on more devices makes a difference. This is very kind of them, & they have great customer follow-up. -Account holder's progeny.
As a result, it is observed that the long-term exposure to Wi-Fi 2.4 GHz Radiofrequency radiation caused an increase in the DNA damage of the brain, liver, kidney, and skin tissue of rats, but this increase was not significant. Therefore it is determined that the long-term exposure to Wi-Fi 2.4 GHz Radiofrequency radiation does not cause the DNA damage of the brain, liver, kidney, and skin tissue of the rats. However it is concluded that the long-term usage of 2.4 GHz Radiofrequency wireless internet providers could cause a potential risk of DNA damage in the testes.
This study used Drosophila as model organisms to assess the effects of various EMF sources (short time daily for 3-7 days) on apoptotic cell death of follicles during oogenesis and reproductive capacity (fecundity) decline. Sources included: 900/1800 MHz mobile phone, 1880-1900 MHz wireless base, wireless handset, mobile phone-handset combination, 2.44 GHz wireless network (Wi-Fi), 2.44 GHz bluetooth, 92.8 MHz FM generator, 27.15 MHz baby monitor, 900 MHz CW RF generator and microwave oven’s 2.44 GHz RF and magnetic field components. All EMF sources used created statistically significant effects regarding fecundity and cell death-apoptosis induction, even at very low intensity levels well below ICNIRP’s guidelines, suggesting that Drosophila oogenesis system is suitable to be used as a biomarker for exploring potential EMF bioactivity.

Although uterine lipid peroxidation increased in the EMR groups, uterine glutathione peroxidase activity (4th and 5th weeks) and plasma prolactin levels (6th week) in developing rats decreased in these groups. In the maternal rats, the plasma prolactin, estrogen, and progesterone levels decreased in the EMR groups, while the plasma total oxidant status, and body temperatures increased. There were no changes in the levels of reduced glutathione, total antioxidants, or vitamins A, C, and E in the uterine and plasma samples of maternal rats.
The following is an excerpt of a typical conclusion published in a scientific journal about the links between EMFs, cell phones and health: "Epidemiologic research shows a low degree of association, inconsistency and missing dose-effect relations. A biologic mechanism of action is still debatable. No harm to human health has been shown. Conclusion: There is no scientific basis as to the harmful effects of EMFs on human health."
